Description

보 접합 장치{A DEVICE FOR COUPLING BEAM ON COLUMN}Beam joining device {A DEVICE FOR COUPLING BEAM ON COLUMN}

본 발명은 보 접합 장치에 관한 것으로, 보다 상세하게는 각형기둥에 보를 접합할 때 사용되는 보 접합 장치에 관한 것이다.The present invention relates to a beam joining device, and more particularly, to a beam joining device used when joining a beam to a square pillar.

일반적으로 건축 구조물은 철골 기둥과 철골 보로 구성된 골조를 구비한다.In general, a building structure has a frame composed of steel pillars and steel beams.

상기한 철골 기둥은 H 형강을 바로 기둥재로 사용하는 형강 기둥, 원형 또는 사각형의 강관 기둥 그리고 I 형강 또는 앵글 채널(angle channel) 형강 등에 철판을 덧대어 만든 조립기둥 등이 있다.The steel column includes a steel pillar using H-shaped steel as a pillar material, a round or square steel pipe pillar, and an assembly column made of an iron plate, such as an I-shaped steel or an angle channel steel.

또한, 철골 보는 형강보와 조립보로 크게 대별되는데, 형강보는 플랜지(flange)와 웨브(web)로 구성되며, 조립보는 래티스(lattice)보, 트러스(truss)보, 및 허니 컴(honey comb)보 등이 있다.In addition, steel beams are roughly classified into girder beams and assembled beams, which are composed of flanges and webs, and assembler beams are made of lattice beams, truss beams, and honey combs. There is a beam.

그런데, 사각형의 강관기둥, 즉 각형기둥과 H 형강보로 골조를 구성하는 경우, 각형 강관기둥의 폐단면 형상 특성상 시공성이 우수한 볼트접합이 어렵기 때문에 대부분 용접에 의한 작업이 이루어진다.By the way, when the frame is composed of a square steel pipe pillar, that is, a square pillar and an H-beam, the welded work is mostly performed because it is difficult to weld bolts with excellent workability due to the closed cross-sectional shape characteristics of the square steel pipe pillar.

이에 따라, 시공 작업이 어렵고 복잡할 뿐만 아니라 각형 강관기둥과 H 형강보의 용접 접합시 용접열에 의해 부재, 즉 각형 기둥과 형강보의 소성변형 능력이 저하되어 내지진 성능저하를 야기하는 문제가 있다.Accordingly, the construction work is difficult and complicated, and there is a problem in that the plastic deformation ability of the member, that is, the square column and the steel beam, is degraded due to the heat of welding during the welding joint of the square steel pipe pillar and the H-beam steel beam, thereby causing the performance degradation. .

본 발명은 형강보와 각형 강관기둥을 보다 용이하게 접합시켜 시공성을 향상시킬 수 있는 보 접합 장치를 제공하는 것을 목적으로 한다.An object of this invention is to provide the beam joining apparatus which can join a shaped beam and a square steel pipe column more easily, and can improve workability.

또한, 본 발명은 형강보와 강형 강관기둥의 접합부에서 발생되는 소성변형을 감소시킬 수 있는 보 접합 장치를 제공하는 것을 목적으로 한다.In addition, an object of the present invention is to provide a beam joining device that can reduce the plastic deformation generated at the junction of the section beam and the steel pipe column.

상기 체결부재는 상기 상기 몸체부와 상기 각형 강관기둥을 접합시키는 원 사이드(ONE-SIDE) 볼트일 수 있다.The fastening member may be a one-side bolt that joins the body portion and the square steel pipe pillar.

상기 상,하부 접합보조부재는 T 자 형상의 단면을 가질 수 있다.The upper and lower joining auxiliary members may have a T-shaped cross section.

상기 연장부와 상기 상,하부 접합보조부재는 볼트와 너트에 의해 또는 용접에 의해 접합될 수 있다.The extension part and the upper and lower joining auxiliary members may be joined by bolts and nuts or by welding.

본 발명에 따르면, 상,하부 접합보조부재를 통하여 형강보를 각형 강관기둥에 접합시킬 수 있어 보다 용이하게 형강보를 각형 강관기둥에 접합시킬 수 있으므 로 시공성이 향상되는 효과가 있다.According to the present invention, the upper and lower joining support members can be joined to the square steel tube pillar through the upper and lower joining support member, so that the steel beam can be easily joined to the square steel tube pillar, thereby improving the workability.

(10) can be bonded.

이에 따라, 형강보(20)를 보다 용이하게 각형 강관기둥(10)에 접합시킬 수 있다.Thereby, the shaped steel beam 20 can be joined to the square steel pipe column 10 more easily.

상부 접합보조부재(140)는 하부 접합보조부재(120)의 상부에 배치되도록 각형 강관기둥(10)에 체결부재(150)에 의해 접합되는 몸체부(142)와, 형강보(20)의 상부 플랜지(22)와 접합되는 연장부(144)를 구비할 수 있다.The upper joint subsidiary member 140 is the body portion 142 is joined to the square steel pipe pillar 10 by the fastening member 150 to be disposed on the upper part of the lower joint subsidiary member 120, the upper portion of the beam beam 20 It may have an extension 144 joined to the flange 22.

즉, 상부 접합보조부재(140)도 'T'자 형상의 단면을 가지도록 형성될 수 있다.That is, the upper bonding auxiliary member 140 may also be formed to have a 'T' shaped cross section.

또한, 연장부(144)는 보(20)의 상부 플랜지(22)와의 나사결합을 위한 체결홀(144a)을 구비할 수 있으며, 상부 접합보조부재(140)와 형강보(20)는 나사체결에 의해 접합될 수 있다.In addition, the extension part 144 may include a fastening hole 144a for screwing with the upper flange 22 of the beam 20, and the upper joining auxiliary member 140 and the shaped steel beam 20 are screwed. Can be joined by.

그리고, 몸체부(142)는 체결부재(150)에 의해 각형 강관기둥(10)에 접합될 수 있도록 나사홀(142a)을 구비할 수 있다. 즉 형강보(20)가 하부 접합보조부재(120)에 안착된 상태에서 작업자는 상부 접합보조부재(140)를 각형 강관기둥(10)에 접합하는데, 이때 작업자는 체결부재(150)를 통해 상부 접합보조부재(140)를 각형 강관기둥(10)에 접합한다.The body 142 may include a screw hole 142a to be joined to the square steel pipe column 10 by the fastening member 150. That is, in the state in which the steel beam 20 is seated on the lower joining auxiliary member 120, the worker joins the upper joining auxiliary member 140 to the square steel pipe pillar 10, in which the operator places the upper part through the fastening member 150. Joining auxiliary member 140 is bonded to the square steel tube pillar (10).

한편, 체결부재(150)는 고장력 볼트인 원 사이드 볼트(ONE-SIDE BOLT)일 수 있다.Meanwhile, the fastening member 150 may be a one-side bolt, which is a high tension bolt.

상기한 바와 같이, 체결부재(150)를 통해 상부 접합보조부재(140)를 각형 강관기둥(10)에 접합시킬 수 있으므로, 용접시 발생되는 용접열에 의해 각형 강관기둥(10)과 보(20)에 발생되는 소성능력 저하를 방지할 수 있다. 이에 따라 각형 강관기둥(10)과 보(20)의 내지진 성능을 향상시킬 수 있다.As described above, since the upper joining auxiliary member 140 may be joined to the square steel tube pillar 10 through the fastening member 150, the square steel tube pillar 10 and the beam 20 by welding heat generated during welding. It is possible to prevent the deterioration of the firing capacity generated in the. As a result, it is possible to improve the performance of the square steel pipe pillars 10 and the beams 20.

또한, 상부 접합보조부재(140)는 체결부재(150)에 의해 각형 강관기둥(10)에 접합되고, 하부 접합보조부재(120)는 용접에 의해 각형 강관기둥(10)에 접합되므로 하부 접합보조부재(120)와 각형 강관기둥(10)의 접합면에서의 접합강도가 상부 접합보조부재(140)와 각형 강관기둥(10)의 접합면에서의 접합강도보다 클 수 있다.In addition, the upper joining auxiliary member 140 is joined to the square steel pipe pillar 10 by the fastening member 150, the lower joining auxiliary member 120 is joined to the square steel pipe pillar 10 by welding, so the lower joining auxiliary Bonding strength at the joining surface of the member 120 and the square steel tube pillar 10 may be greater than joining strength at the joining surface of the upper joining auxiliary member 140 and the square steel tube pillar 10.

이에 따라, 지진하중에 의하여 더 많은 하중이 전달되는 하부 접합보조부재(120)와 각형 강관기둥(10)의 접합부의 파손을 방지할 수 있다.Accordingly, it is possible to prevent breakage of the joint between the lower joining auxiliary member 120 and the square steel pipe pillar 10 to which more load is transmitted by the earthquake load.

상기한 바와 같이, 하부 접합보조부재(120)의 상부에 보(20)를 안착시킨 상태에서 보(20)를 각형 강관기둥(10)에 접합시킬 수 있으므로, 시공성이 향상된다.As described above, since the beam 20 can be bonded to the square steel pipe column 10 in a state in which the beam 20 is seated on the upper portion of the lower joining auxiliary member 120, the workability is improved.

또한, 보(20)가 상,하부 접합보조부재(120,140)를 통해 각형 강관기둥(10)에 접합되므로, 지진하중이 전달되면 보 접합 장치(100)가 항복되어 각형 강관기둥(10)이 파괴되는 것을 방지할 수 있다.In addition, since the beam 20 is joined to the square steel pipe pillar 10 through the upper and lower joining auxiliary members 120 and 140, when the earthquake load is transmitted, the beam bonding device 100 is yielded and the square steel pipe pillar 10 is destroyed. Can be prevented.
